People Also Ask
People Also Ask (PAA) is a Google SERP feature that displays an accordion of questions related to a user's search query; clicking a question expands a short answer excerpted from a specific web page along with a link to its source. New questions are added dynamically with each click, so the box expands almost endlessly.
- People Also Ask (PAA) is a Google search feature that groups questions related to a query into an accordion and, when clicked, expands an answer excerpted from a source page.
- Each time a question is opened, new questions are appended automatically, making the box expand almost infinitely as Google's machine learning analyzes follow-up search patterns.
- It is common enough that PAA appears in roughly 43% of all queries per Ahrefs and about 51.85% per Semrush Sensor (August 2024).
- PAA answers are usually pulled from pages that already rank in the top 10 for the question, and like featured snippets they appear as paragraphs, lists, or tables.
- Using the exact question as a heading, providing a direct answer, and matching the existing answer format are the core tactics for improving your odds of being featured.
Definition
People Also Ask (PAA for short) is a Google SERP feature that presents questions related to a user's query as a collapsed accordion. Clicking any question expands a short answer excerpted from a specific web page along with a link back to its source. At the same time, new questions are added dynamically at the bottom of the box, so a single search lets users keep drilling down into a chain of related questions.
PAA often appears alongside featured snippets, but it is a distinct feature. Google refers to it as a "related questions group," and it can surface in a range of positions, including near the top of the results.
How It Works
The PAA box is not a static list but a self-generating, dynamic component. When a user expands one question, related questions are populated below it, and as this repeats the box effectively keeps growing without end. What makes this infinite expansion possible is not simple keyword association but Google's machine learning, which analyzes real user search patterns. The algorithm tracks what users search for after their initial query, identifies knowledge gaps, and surfaces questions that fill those gaps.
Answers are excerpted from the page Google judges to best match a given question, and for the same question it tends to use the same source page consistently across multiple queries. Answer formats vary as well, appearing as paragraphs, bulleted lists, tables, images, or videos, much like featured snippets.
Comparison with Featured Snippets
| Aspect | Featured Snippet | People Also Ask (PAA) |
|---|---|---|
| Placement | Usually at the very top of results (position zero) | Various positions starting near the top, as a cluster of questions |
| Structure | A single answer to a single question | Multiple questions in an accordion that expands dynamically |
| Interaction | Shown already expanded | Answer expands only after a click |
| Source page | One page that best fits the question | Excerpted per question from pages in the top 10 |
Key Statistics
PAA is currently one of the most common SERP features in Google Search. According to Ahrefs Keywords Explorer data, a PAA box appears in roughly 43% of all queries. Data measured by Semrush Sensor in August 2024 found PAA in about 51.85% of all searches, confirming that depending on the measurement period and method, it shows up in around half of all queries, a substantial share.
That said, the actual click-through rate is not high relative to how often PAA appears. A Backlinko study cited by Ahrefs found that on average only about 3% of searchers interact with the PAA box, though this varies widely by query, climbing as high as 13.6% for some terms. Ahrefs estimates that earning 100 clicks from PAA boxes would require appearing for questions spanning keywords with a combined monthly search volume of roughly 33,000.
Optimization Tactics
The core tactics Semrush recommends are as follows.
- Use questions as headings: Repurpose the questions that appear in PAA directly as your page's h2 and h3 headings to clearly signal topical relevance to Google.
- Provide a direct answer: Place a clear, concise answer to the question immediately below the heading to improve the chance of a match.
- Match the existing answer format: Check whether the answer currently shown in PAA is a paragraph, a list, or a table, and write in the same format to increase the likelihood of being excerpted.
- Optimize images: Use descriptive alt text and meaningful file names so your images have a chance to be surfaced alongside the answer.
Ahrefs further emphasizes that PAA answer sources are mostly pages already ranked in the top 10 for the question. In other words, a precondition for PAA visibility is already holding a high ranking for the question keyword and having a page that contains an answer in the format Google expects.
Implementation Checklist
- Collect the PAA questions that actually appear for your target topic and reflect them in your content structure.
- Place each question as a heading with a direct 40-60 word answer immediately below it.
- Check the format of the answer currently shown (paragraph, list, or table) and write in that same format.
- Strengthen body depth and authority to target a top-10 ranking for the question keyword.
- Assign descriptive alt text and meaningful file names to your images.
